Ambry Genetics

Apr 25, 2023

The c.365G>A (p.R122Q) alteration is located in exon 4 (coding exon 4) of the FAM92A1 gene. This alteration results from a G to A substitution at nucleotide position 365, causing the arginine (R) at amino acid position 122 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
